More Power and Torque. The SLP X-Pipe uses free-flowing mandrel-bent tubing with a genuine X style crossover and high-flow catalytic converters to provide a significant increase in horsepower and torque over the restrictive stock catted pipes.

Race Car Growl. This free flowing SLP x-pipe for the 1996 to 1998 Mustang's not only increases power, but it also adds a raspy, race car growl to the sound of your exhaust with its modern "X" crossover pipe design.

Upgradable Modular Design. SLP's exclusive three-piece modular design makes it possible to easily upgrade to SLP's Long-Tube Headers without the need of purchasing a brand new X-Pipe by just removing the down pipes. This unique modular design also makes it easy to install this X-Pipe on your Mustang with just basic hand tools.

Application. This Catted X-Pipe from SLP is designed as a direct bolt-on for the 1996-1998 GT and 1996-1998 SVT Cobra Mustangs with either aftermarket short tube headers or the stock manifolds and a dual catback exhaust installed.

Do not buy if you car is Lowered

These pipes hand REALLY low, I had less than 1 1/2 inches between the ground and the cats, and they sit substantially lower that the stock exhaust, about two inches lower in fact. Needless to say they ...
last me about a week before i more or less high centered it trying to get over a speed bump and completely destroyed the passenger side catalytic. You can do a search on this and see that this is a design flaw in the product and not a issue on only a couple. Spend the extra money and buy a BBK or a Bassani, they fit much better.

Installation Concerns I bought my Cobra back in November, and the Catalytic Converters have went because of the awful Stock H-pipe, I'm looking into a new mid pipe for the car and was wondering if this would fit replacing the stock H-pipe with the rest of the exhaust being stock.

clearance and looks Do the cats hang lower than the frame? Do they bolt up the stock manifold

InZspot

I am lowered 1.75 inches. They do hang lower than the frame. I barely got it back off the lift. However with stock height i would see no real problem. They do bolt right up, no issues with the installation. Not a bad idea to put a few coats of some penetrating lube on all the bolts though.

Paired this x-pipe with slp lm1 and it sounds soooo good. didn't seem very loud in the car, most of the noise is out the back. Had a friend drive mine while i followed him and it makes some sweet noise starting around 2500 rpm. Will definately buy slp for future mustangs as well. And as always fast/free shipping from AM.

It would help out a lot if they would say in the directions that it was going to be such a pain to get the stock cats off the car, and if you dont have a compressor and impact gun good luck. Also pre-spraying everything with a penetrating oil to start with will greatly increase the speed at which these bolts will come off the car. Look and tone of product great.

1998 Mustang GT- Easy to install and adjust, way harder to remove factory H-Pipe. The Tone Is absolutely perfect, you get alot of heads turned and compliments, I have my x-pipe paired with the American Thunder Cat-back. I would recomend this pipe to all Mustang owners.

Installed on a 98 Cobra. Completely impressed. Item is 10-12 pounds lighter than stock, reduces heat, good fit, EXCELLENT sound (coupled to Flowmasters), louder but not overly loud or droning, no vibrations, exhaust note is clean and sharp. Huge upgrade over the stock pipe(which has pre-cats). The pipe made NOTICABLE power.

The x-pipe and Loudmouth exhaust are awesome. They really sound amazing. I can't believe its the same car. Well worth the money. Brings a huge smile to my face everytime I start up my Cobra and drive it around.

Pros
Exhaust sound
Flexibility with being able to swap the cats for straight pipes
Cons
Fitment
Hangs way to low compared with stock
After years of having this on. Finally got fed up with the bad fitment and rubbing on everything. Gonna spend the extra money and get a magnaflow which has the provisions for the factory bracket in my 96 gt.

Well... Recently installed on my 97 gt convertible that already had the LM'S cat back on it. Love the quality and the sound. However it's not a good idea if you plan on lowering or are already lowered. They definitely sit lower than what I like. I'm lowered 1.75 inches and speed bumps are a no-no. Without the cats would save a couple inches but with my vert I'm afraid it will be a little loud for the kids. The cats are easily removable though.

This is a great three piece mid-pipe from SLP. The performance gain was felt in my 98 gt. With mine i also got the race pipe inserts which allows you to take out the cats to make a off road Xpipe. I would highly recommend this product to anyone!
And of course AM.com has the best shipping times than anyone!

This X pipe sounds great and if you have to have cats for emissions this is the mid pipe you want. when they say easy install they mean it. It was 10X easier to install than to get that stock H Pipe off.

Word on The Street

When you order from American Muscle, there is an excellent variety of top quality products from which to chose. You can count on getting a fair price coupled with excellent, low priced shipping. I have found their customer service people to be cheerful, extremely knowledgeable, .and easy to work with. They tend to be problem solvers and don't just quote inflexible corporate policy. I'm very impressed.

I have always been into cars, specifically Mustangs. But it wasn’t until I owned my first mustang that I really got in to them. I was I need of a car at the time and knew someone who owned a dealership and he had a 2000 Mustang convertible there. Being my first Mustang I didn’t know much about them...
